Title: Rotary driving heads for drill strings
IPC: E21B19/16
Filed: 1974-12-24
Abstract: 1464149 Rock drilling; making up pipe joints TRW Inc 24 Dec 1974 [26 Dec 1973] 55696/74 Headings B3C and B3N [Also in Division E1] A rotary driving head, e.g. for a rock drill, has a drive spindle 15 having a threaded end portion 42 for connection to a threaded connector 43 on a drill pipe 46, and a reciprocable splined plunger 34 mounted in the drive spindle 15 for movement between a retracted position (not shown) and an advanced position (Fig. 1) in which the plunger 34 engages spines 47 in the drill pipe connector 43, thus locking the drill pipe 46 and spindle 15 against relative rotation, e.g. when breaking pipe joints in the drill string. As described the spindle 15 is driven by a hydraulic motor 13 via planetary gear set 12, shaft 14, bushing 21 and keys 19, 20. The plunger 34 is slidable in a chamber 16 in the spindle 15, a splined collar 36 fixed to spindle 15 by pin 38 preventing relative rotation between the plunger 34 and spindle 15. The plunger 34 is biased towards its retracted position by spring 35 and is moved to its advanced position by supplying pressure fluid through lines 50 and ports 51, 53. The rotary driving head 80 (Fig. 4) is movable vertically along a mast 81, by a cable and pulley system (not shown), the apparatus also including pipe gripping means 82 (Fig. 4a) consisting of jaws 83, 84 moved together by piston and cylinder 87. The drill string is withdrawn from the borehole 91 as follows: first the pipe joint 92 between sections 88, 90 is positioned below the pipe gripper 82 (Fig. 4) which is then actuated. The motor of head 80 is then rotated (with plunger 34 retracted) in the reverse direction through half a turn to loosen the joint 89 between drive spindle 42 and pipe section 88. The head 80 is then raised until the joint 92 is above the grippers 82 which are again actuated. Plunger 34 is then extended and the motor is driven in reverse to loosen and unscrew the joint 92, torque from the motor being transmitted to the pipe section 88 via plunger 34 and splines 47. The plunger 34 is then retracted and the motor is again driven in reverse to unscrew the joint 89. The pipe section 88 can then be removed and the head 80 is then lowered and connected to the next section 90 by driving the motor forwardly. The head 80 is then raised to withdraw pipe section 90 from the borehole, this procedure being repeated until the entire string is removed from the borehole.

Abstract: 1,172,420. Releasable fastenings. J. ZELLER. 18 Dec., 1967 [5 Jan., 1967], No. 57353/ 67. Heading E2A. A device for detachably connecting a first and a second element comprises a hook member 3 and a covering member 7 for connection to said first element, a retaining member 8 for connection to said second element whereby the hook member and covering member can engage the retaining member and the covering member is movable relative to the hook member to a position in which it covers the hook member and thus renders the hook member inoperative so that the hook' member and covering member can be disengaged from the retaining member. As shown the covering member 7 is long enough so that its end portion can enter the hook of the hook member so that when the hook and covering member are pushed under and beyond the retaining member, a reverse movement will engage the hook with the retaining member, the release of the hook from the retaining member being accomplished by first pushing the hook beyond the retaining member then moving the covering member so that it closes the mouth of the hook and then moving the hook and covering member in the reverse direction, the covering member preventing the hook engaging the retaining member. One of the elements is the flap 2 of a pouch 1 and the element 1 is the remainder of the pouch; the retaining member is a strap connected at both ends to the element 1. In a modified construction the hook member is disposed so that its mouth is on the opposite side of the member 3 to that shown and the covering member is also on the corresponding side of the member. 3; instead of the retaining element being a single strap two superimposed straps are used and the hook and covering member are passed between and beyond the two straps, the hook on the return movement engaging the underneath strap.
